🛠️ Issues resolved
| Product area | Description | Resolution |
|---|---|---|
| Backup & Restore | Scheduled and manual appliance backups failed after the Discovery scanner agent was upgraded, with backup logs reporting access denied errors for the Discovery database and registry. | Backups now complete successfully after a Discovery scanner agent upgrade, with proper access to Discovery database and registry data. |
| Backup & Restore | On the Edit Backup screen, previously deselected backup options displayed as selected, even though the saved schedule did not include them. | The Edit Backup screen now correctly displays each backup option's saved selection state. |
| High Availability | HA pairing could stall indefinitely with no error message when the firewall configuration or partner reset steps took longer than expected, particularly on heavily loaded appliances. | HA pairing now tolerates slow firewall configuration and partner reset operations and displays a clear failure message if pairing cannot complete in time. |
| Security & Compliance | Password Safe appliances running on Windows Server 2022 allowed connections using the outdated HTTP/1.0 protocol. | Password Safe appliances no longer accept HTTP/1.0 connections on Windows Server 2022. |
